A Concise Review on the Use of Mesenchymal Stem Cells in Cell Sheet-Based Tissue Engineering with Special Emphasis on Bone Tissue Regeneration

The integration of stem cell technology and cell sheet engineering improved the potential use of cell sheet products in regenerative medicine. This review will discuss the use of mesenchymal stem cells (MSCs) in cell sheet-based tissue engineering. Besides their adhesiveness to plastic surfaces and their extensive differentiation potential in vitro, MSCs are easily accessible, expandable in vitro with acceptable genomic stability, and few ethical issues. With all these advantages, they are extremely well suited for cell sheet-based tissue engineering. This review will focus on the use of MSC sheets in osteogenic tissue engineering. Potential application techniques with or without scaffolds and/or grafts will be discussed. Finally, the importance of osteogenic induction of these MSC sheets in orthopaedic applications will be demonstrated

Anti-proliferative and anti-invasive effects of ferulic acid in TT medullary thyroid cancer cells interacting with URG4/URGCP

WOS: 000374593300060PubMed ID: 26334619Ferulic acid (4-hydroxy-3-methoxycinnamic acid; FA), a common dietary plant phenolic compound, is abundant in fruits and vegetables. The aim of present study is to investigate the effects of FA on cell cycle, apoptosis, invasion, migration, and colony formation in the TT medullary thyroid cancer cell line. The effect of FA on cell viability was determined by using CellTiter-Glo assay. IC50 dose in the TT cells was detected as 150 mu M. URG4/URGCP (upregulated gene-4/upregulator of cell proliferation) is a novel gene in full-length mRNA of 3.607 kb located on 7p13. It was determined that FA caused a decrease in the expression of novel gene URG4/URGCP, CCND1, CDK4, CDK6, BCL2, MMP2, and MMP9, a significant increase in the expression of p53, PARP, PUMA, NOXA, BAX, BID, CASP3, CASP9, and TIMP1 genes in TT human thyroid cancer cell line by using real-time PCR. It was found that FA in TT cells suppressed invasion, migration, and colony formation by using matrigel invasion chamber, wound healing, and colony formation assay, respectively. In conclusion, it is thought that FA indicates anticarcinogenesis activity by affecting cell cycle arrest, apoptosis, invasion, migration, and colony formation on TT cells
